November 11, 2005—Luxo has introduced the first task lamp using energy-efficient light-emitting diodes (LEDs), says the company.
Research conducted by Stephen Johnson, a scientist at the Environmental Energy Technologies Division of Lawrence Berkeley National Laboratory, helped lamp manufacturer Luxo USA Corporation develop the LED lighting systems that led to the new product.
Luxo’s LED Arketto uses three 3-watt LEDs but provides more usable light than the comparable 40-watt halogen that it will replace due to the higher efficiency of the source and better optical control of the light.
Lighting researchers believe that as LEDs improve, their application in both residential and commercial spaces could cut worldwide lighting electricity use in half.
Luxo’s Arketto LED resulted from extensive R&D by the manufacturer, with the help of technical advice and support from Johnson. Johnson is head of EETD’s Lighting Group. Luxos corporate headquarters are in Oslo, Norway.
The company’s new LED task light uses LEDs and an advanced reflector design to diffuse the light over a work area about three feet-by-four feet when the head of the lamp is 18 inches from the work plane. At this level, the Luxo LED lamp puts more light on a desk than a 40-watt halogen lamp. The head is mounted on a flexible arm that can be adjusted over the work surface. The Arketto design has won awards for Luxo in a number of interior design competitions.
